CATCH-BASIN.

SPECIFICATION forming part of Letters Patent No. 749,148, dated January12, 1904.

Application filed February 27, 1903. Serial No. l45,f141. (N0 model.)

To all whom, it may concern:

Be it known that I, WILLIAM AYLWARD, Jr. a citizen of the United States,residing at Neenah, in the county of VV'innebago and State of Wisconsin,have invented a new and useful Improvement in Catch-Basins, of which thefollowing is a specification.

My invention relates to catch-basins formed of several sections of castmetal of a cylindrical form, the bottom of the lower section beingsemiglobular or bowl-shaped and being provided with a branch outlethaving a trap connected therewith for preventing the escape of sewer-gasthrough the catch-basin.

It also relates to the combination with the upper section of an annularflange for supporting one or more courses of brick wall in order tobring the top grating at the proper height for receiving the inflow fromthe gutter, the improvements being illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective view of the catchbasin.Fig. 2 is a vertical section in perspective of the catch-basin and itstrap. Fig. 3 is a perspective view of a part of the upper metallicsection with an annular flange mounted thereon and numerous courses ofbrick thereon for bringing the top grating to the proper grade for thestreet-gutter.

Similar numerals indicate like parts in the several views.

1 indicates the lower section of the catchbasin, having a branch 2 forreceiving a castmetal elbow 3 for forming a trap, as shown by thewater-line 4 of Fig; 2, the lowest point of the outlet in said elbowbeing at substantially the level of the upper end of said first section.A section of vitrified or cement pipe 5 is connected with the elbow forleading to the sewer.

The joint between the branch and elbow 3 is to be cemented so as to forma tight 'joint and preserve the water-level necessary for the trap.Above the section 1 any desired number of sections 6 and 7 may be placedin position, the section 1 being provided with an annular flange 8 forreceiving the lower end of section 6, said section 6 receiving the lowerend of section 7, of which any required Among the advantages of mycast-metal catch-basin over the usual brick ones is their lessened costboth of material and the labor of placing them in position, and alsowhen changes in their location are required they can be removed andplaced in a new position with little liability of breakage of any oftheir parts.

As catch-basins in use require to be cleaned of the accumulations fromthe street-wash at short intervals, it is desirable that when done it isentirely cleaned of said accumulations. This cannot be easily done witha flat-bottomed basin; but with a semiglobular bottom and a suitablescoop almost the entire contents can be removed.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. A catch-basin consisting of several cylindrical sections of castmetal, its lower section having an annular flange around its upper end,a semiglobular or bowl-shaped bottom, a branch outlet from one side ofsaid section, and a cast-metal elbow, said outlet and elbow forming atrap, the lowest point in an outlet of said elbow being substantiallyupon a level when placed in position, with the upper end of saidsection, one or more sections above said lower section, the lowest ofwhich is adapted to be held in position by the annular flange of saidlower section, means for bolding succeeding sections in position and asuitable flange having a vertical grating mounted upon the upper end ofthe catch-basin, substantially as described.

2. In a catch-basin, the lower portion of which is formed of cylindricalsections of cast metal, the combination therewith of an annu- Verticalgratings thereon, mounted upon said lar flange mountgd upon theupperfenil 01% the Wall, substantially as set forth. upper one of saisections, means or 10 ing it in position thereon, one or more courses ofAYLWARD 5 brick laid upon said flange and forming a Wall Witnesses:

of substantially the same diameter as said cy- W. E. BROWN, lindricalsections, and a suitable flange having S. B. MORGAN.
